Qualitative Filter Paper - 5226-190
Gravity filtration methods for removing suspended solids require filter paper that seats cleanly in funnels and retains particles consistently. Medium retention grades capture suspended solids while maintaining flow rates suitable for routine laboratory sample throughput requirements. In practice, each sheet reflects production standards where fiber density, thickness, and retention characteristics are verified before lot release.
Key Filter Paper Characteristics
- Basis weight of 87g/m² indicates the fiber mass per unit area that controls retention, flow rate, and wet strength.
- Standard cellulose without surface treatment delivers reliable performance for applications where chemical hardening is not required.
- Wet strength sufficient for gentle handling during precipitate transfer while maintaining the rapid flow rates of qualitative grades.
- Pure cellulose fiber construction delivers consistent flow rates and predictable retention for general sample clarification and preparation.
- Medium porosity cellulose matrix captures suspended solids while maintaining the throughput needed for efficient batch processing.
Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. With these demands in mind, predictable retention and flow rate from a pure cellulose matrix give you a dependable filtration baseline for routine sample preparation. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.
